CVE-2018-16563

https://notcve.org/view.php?id=CVE-2018-16563

A vulnerability has been identified in Firmware variant IEC 61850 for EN100 Ethernet module (All versions < V4.35), Firmware variant MODBUS TCP for EN100 Ethernet module (All versions), Firmware variant DNP3 TCP for EN100 Ethernet module (All versions), Firmware variant IEC104 for EN100 Ethernet module (All versions), Firmware variant Profinet IO for EN100 Ethernet module (All versions), SIPROTEC 5 relays with CPU variants CP300 and CP100 and the respective Ethernet communication modules (All versions < V7.82), SIPROTEC 5 relays with CPU variants CP200 and the respective Ethernet communication modules (All versions < V7.58). Specially crafted packets to port 102/tcp could cause a denial-of-service condition in the affected products. A manual restart is required to recover the EN100 module functionality of the affected devices. Successful exploitation requires an attacker with network access to send multiple packets to the affected products or modules. As a precondition the IEC 61850-MMS communication needs to be activated on the affected products or modules. • https://cert-portal.siemens.com/productcert/pdf/ssa-104088.pdf •

CVE-2018-4838

https://notcve.org/view.php?id=CVE-2018-4838

A vulnerability has been identified in EN100 Ethernet module IEC 61850 variant (All versions < V4.30), EN100 Ethernet module DNP3 variant (All versions < V1.04), EN100 Ethernet module PROFINET IO variant (All versions), EN100 Ethernet module Modbus TCP variant (All versions), EN100 Ethernet module IEC 104 variant (All versions < V1.22). The web interface (TCP/80) of affected devices allows an unauthenticated user to upgrade or downgrade the firmware of the device, including to older versions with known vulnerabilities. Se ha identificado una vulnerabilidad en la variante del módulo de Ethernet EN100 IEC 61850 (todas las versiones anteriores a la V4.30), la variante del módulo de Ethernet EN100 DNP3 (todas las versiones anteriores a la V1.04), la variante del módulo de Ethernet EN100 PROFINET IO (todas las versiones), la variante del módulo de Ethernet EN100 Modbus TCP (todas las versiones) y la variante del módulo de Ethernet EN100 IEC 104 (todas las versiones anteriores a la V1.22). La interfaz web (TCP/80) de los dispositivos afectados permite que un usuario no autenticado actualice o degrade el firmware del dispositivo, incluyendo versiones más antiguas con vulnerabilidades conocidas. • https://cert-portal.siemens.com/productcert/pdf/ssa-845879.pdf https://ics-cert.us-cert.gov/advisories/ICSA-18-067-01 https://www.securityfocus.com/bid/103379 • CWE-306: Missing Authentication for Critical Function •
